Wednesday, another day @jaxkonferenz.bsky.social, kicking off with @tastapod.com trying to convince us to build the "Best Simple System for Now".
Q: "Can you pass the salt?"
A: "I'm developing a system... that'll save you time in the long run"
"This time it's different" 😍 😊

Welcome to W-JAX!
Rod Johnson kicking off with his keynote about AI-agents and the future of Java.
And how right now most Gen-AI are failing spectacularly. We need more than "This time it's different".
Let's start with attacking non-determinism. And see how Embabel can help us 😍

Today is election day in The Netherlands. Whenever you have the chance, I urge you to vote, just like I did today!
Vote for the future of our planet, vote liberal, vote against climate change, against hate and, especially, vote against the toxic lies that are killing humanity.

Unbelievable, it's already the end of conference day 2 @devoxx.com 🥲
Fortunately tomorrow is another day and today, we still have a movie to look forward to as well. 🎥 🎬 🥳
But first, we're all enjoying @adambien.blog in an AI / LLM free talk with Java shorts. Almost.

Watching @brianvermeer.nl talking @devoxx.com about "advanced" prompt injection in AI and LLM's...
By just repeating the same prompt twenty times, it'll suddenly comply to your malicious prompt. Yes!

Fortunately I’m not already filled, but still hungry for a bit of food for thought. 🥐🥧
So, let's have a few more morsels of tasty code about OpenAI, Langchain4j and JSON schema's. 😍

Another day @devoxx.com, another session about agentic systems, this time by the langchain4j heroes @kevindubois.com and Mario Fusco.
Always good to start with a definition, to get everyone on the same page.
And now into the code 🎉.

Pondering this morning's ☕ session by @nipafx.dev
The AOT caching feature, and specifically loading aot files, somehow feels like a hacker's paradise in the making. It reminds me of all the deserialization issues we had way back when. Or am I too sceptical?
